FRED SEXTON, .OF BENTON PATENT OFFICE.

, ILLINOIS.

LAMENY-PROOF LOGKIN G APPARATUS.

To all whom it may concern:

Be it known that I, FRED SEXTON, a citizen of the United States, residing at Benton, in the county of Franklin and State of Illinois, have invented new and useful I1nprovements in Larceny-Proof Locking Apparatus, of which the following. is a specification.

This invention has for its object to provide an improved locking device especially designed for application to the coil box of the ignition system of a motor vehicle to prevent the operation of the vehicle by unauthorized persons.

Another and more specific object of the invention is to provide a locking device wherein the vibrators of the coils are locked in inoperative position so as to prevent the vibratory'movement necessary to the successful operation of the coils.

Another ob'ect is the provision of a looking device 0 this character which, when released, is held in inoperative position permitting usual operation of the explosive enine. I b With these and other objects in view, as will appear" as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described herein and set forth with particularity in the claims appended hereto.

eference 1s had to the accompanying drawings forming a part of this specification, in which like reference characters indicate the corresponding parts throughout the several views, in which Figure 1 represents a plan view of the vibrator actuating shaft.

Figure 2 represents a vertical transverse sectional view through the dash board of a motor vehicle illustrating the improved locking device applied to. the coil box,

lgure 3 represents a coil box, partly in section, and 7 4 Figure 4 represents a front elevation of the coil box, partly in section, showing the invention applied thereto.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a conventional type of coil box forming a part of the standard equipment of motor vehicles practically known in the trade as Ford auto- As usu t e b i PW- at Specification of Letters Patent.

the rear of the dash board 6 and is provided with circular vibrators 7 forming part of the induction coils which are housed within the box 5 and form part'of the ignition system of a motor vehicle (not shown).

In applying the invention to use, an apertured bearing member 8 is secured to the dash board 6 at one side and adjacent the top of the box 5 and pivotally supports one terminal of a lock shaft 9 which extends across the top of the box 5 under the cover thereof and is received within suitable recesses formed in the upper edge portions of the end walls of the box.

The opposite terminal of the'shaft is directed angularly as at 10, extends downwardly along the opposite end wall of the box 5 and is formed with a slot 11 engageable over an eye-bolt 12 secured to the dash board 6 and provided with an eye of such internal diameter as to receive the shackle of a preferred type of lock 13 whereby the an ular terminal of the arm 10 may be 100 edin depressed position and in contact with the dash board 6.

To prevent the removal of the bearing member 8 or the eye-bolt 12 from the dash board of the vehicle by unauthorized persons, the bolts by which these parts are secured in position are preferably upset at their terminals and subsequent to the application of nuts thereto and are preferably constructed of such hard metal as to prevent cutting of the bolts by such ordinary tools as cold chisels or hack saws.

The body portion of the shaft 9 is formed with a plurality of pairs, of radiating pins 14 corresponding in number to the number of vibrators 7 and so arranged as to engage and depress said vibrators when the arm or angular extremity 10 of the shaft is moved downwardly over the eye-bolt 12 so as to hold the vibrators against vibratory movement and effectively prevent operation of the engine.

A coil spring 15 is arranged about the vibrator engaging pins 14 out of engagement with the vibrators 7 and of the vehicle.

In use, the lock 13 is removed from the eyebolts 12 and the shaft? is looked to such poi permit operation sition under the influence of the spring 15 so as to disengage the pins 14 from the vibrators 7 and thus permit operation of the vehicle. However, when it is desired to lockthe v1- brators against movement and thus prevent operation of the vehicle by unauthorized persons, the arm 10 is depressed-against the tension of the spring engaging the eye-bolt 12 in the slotted terminal 11 thereof and by subsequently applying the lock 13 to the bolt the shaft is locked insuch position to prevent vibratory movement of the vibrators 7.

What I claim is:

1. The combination with a coil box and vibrator of the ignition system of an exploslve engine, of lock controlled means to retam the vibrator against vibratory movement and prevent operation of the engine.

2. The combination with a coil box and vibrator of the ignition system of an explosive engine, of means engageable with the vlbrator to prevent vibratory movement thereof, means to lock the first mentioned means 1n such position as to prevent vibratory movement of the vibrator, and means normally tending to move the first mentioned means to inoperative position.

3. The combination with a coil box and vibrator of the ignition system of an explos ve engine, of means for engaging and retaining the vibrator against vibratory movement, and releasable means for locking the engaging means in such position as to prevent v1- bratory movement of the vibrator.

4. The combination with the coil box and vibrator of the ignition system of an explosive engine, of a rock shaft, means carried by said rock shaft to engage and prevent vibratory movement of said vibrator, and means to lock said shaft in operative position preventing vibratory movement of the vibrator.

5. The combination with the coil box and vibrator of .the ignition system of an explosive engine, of a rock shaft, means carried by said shaft to engage and prevent vibratory. movement of the vibrator, releasable means to lock the shaft inoperative position preventin movement of the vibrator, and means norma ly tending to move the shaft to' inoperative position.

6. The combination with the coil box and vibrator of the ignition system of an explosive engine, of a rock shaft, means carried by the rock shaft for engaging and retaining the vibrator against movement to prevent operation of the engine, an arm carried by the shaft, means engageable with-the arm to lock the shaft in operative position preventing movement of the vibrator.

7 The combination with the coil box and vibrator of the ignition system of an explosive engine, of a rock shaft, means carried by the rock shaft for engaging and retaining the vibrator against movement, an arm carried by the rock shaft, releasable means engagea le with the arm to retain the latter in operative position to prevent movement of the vibrator, and means normally tending to move the arm in such position as to permit vibratory movement of the vibrator.

8. The combination with the coil box and vibrator of the ignition system of an explosive engine, of a rock shaft, means carried by the rock shaft for engaging and retaining the vibrator against movement, an arm carried by the rock shaft, means engageable with the arm to lock the shaft in operative position preventing movement of the vibrator, and

means normally tending to elevate the arm to release the vibrator.
